  • Patent number: 10240065
    Abstract: We have demonstrated reversibly reducing metal-ion crosslinkages in polymer systems, by harnessing light, creating a dynamic and reversible bond. The reduction induces chemical and physical changes in the polymer materials. Some variations provide a polymer composition comprising: a polymer matrix containing one or more ionic species; one or more photosensitizers; and one or more metal ions capable of reversibly changing from a first oxidation state to a second oxidation state when in the presence of the photosensitizers and light. Some embodiments employ urethane-based ionomers capable of changing their crosslinked state under the influence of a change in counterion valance, using light or chemical reducing agents. This invention provides films, coatings, or objects that are reversible, re-mendable, self-healing, mechanically adjustable, and/or thermoplastic/thermoset-switchable.

  • Publication number: 20130046034
    Abstract: A process for creating polyolefin blends from waste streams with controlled rheological properties can include processing a waste stream to make a mixture comprising a mixture comprising polypropylene and polyethylene and compounding the mixture with one or more peroxides or nitroxides to produce a polyolefin blend. For example, a process can include: determining the required melt flow rate of the end product; determining the ratio of polyethylene to polypropylene to achieve the required melt flow rate; effecting a separation of polypropylene from polyethylene to achieve the desired composition; determining the amount of peroxide or peroxide concentrate required to increase the melt flow rate to the required level; melt compounding the mixture; evaluating the melt flow rate of the product; and adjusting the composition of polyethyelene and polypropylene or the amount of peroxide added if necessary to achieve the required melt flow rate.
